Re: [R] Draw a circle with a given radius in an existing map

I'd very much appreciate your response. You want the circle to appear to be a circle on the plot, or an accurate representation of a circle on the ground (which may not be circular when plotted)? Uwe answered the former. I don't know the answer to the latter, but surely someone does...
